The Adiri™ Natural Nurser™ Ultimate Baby Bottle is soft, safe and simple. With an easy to use and dishwasher safe Fill Twist and Feed™ system, the only nipple truly shaped like a mother's breast, soft phthalate-free and BPA-free materials, and a unique Petal vent that helps reduce colic, the Adiri Natural Nurser enables the ultimate bottlefeeding experience. A sleek cover protects the bottle from getting dirty and keeps the nipple from leaking during transport. The Adiri Natural Nurser comes in three stages for three different flow rates and is color coded by flow rate (stage 1, white; stage 2, blue; stage 3, orange). Each stage holds 8 oz. of fluid and is dishwasher safe! Adiri Natural Nursers can also be boiled or sterilized using a basic sterilizer.

Stage Three (Fast Flow) is generally used for babies 6 months and older.
